JQI welcomes four newest Fellows

JQI has named four new Fellows in 2019, bringing the total number to 35. All four of the new arrivals have appointments in the Department of Physics at the University of Maryland. One Fellow is also a professor in the Department of Electrical and Computer Engineering at UMD and another is a physicist at the National Institute of Standards and Technology (NIST).

Ions clear another hurdle toward scaled-up quantum computing
Scientists demonstrate parallel entangling operations on a small quantum device.

Scientists at the Joint Quantum Institute (JQI) have been steadily improving the performance of ion trap systems, a leading platform for future quantum computers. Now, a team of researchers led by JQI Fellows Norbert Linke and Christopher Monroe has performed a key experiment on five ion-based quantum bits, or qubits. They used laser pulses to simultaneously create quantum connections between different pairs of qubits—the first time these kinds of parallel operations have been executed in an ion trap. The new study, which is a critical step toward large-scale quantum computation, was published on July 24 in the journal Nature.    ... Continue Reading

Corkscrew photons may leave behind a spontaneous twist

Everything radiates. Whether it's a car door, a pair of shoes or the cover of a book, anything hotter than absolute zero (i.e., pretty much everything) is constantly shedding radiation in the form of photons, the quantum particles of light.A twin process—absorption—is usually also present. As photons carry away energy, passers-by from the environment can be absorbed to replenish it. When absorption and emission occur at the same rate, scientists say that an object is in equilibrium with its environment. This often means that object and environment share the same temperature.Far away from equilibrium, new behaviors can emerge. In a... Continue Reading

Second annual trapped-ion conference comes to UMD

The University of Maryland will host the 2nd North American Conference on Trapped Ions (NACTI) from July 22-26. This year’s conference comes two years after the inaugural meeting, which was held on the Boulder, Colorado campus of the National Institute of Standards and Technology (NIST).More than 230 students and researchers from around the globe, all working on the science of trapped atomic ions, will attend five days of sessions at the Edward St. John Learning & Teaching Center on campus at UMD.

Gorshkov receives early-career research award

Alexey Gorshkov, a JQI Fellow and a Fellow of the Joint Center for Quantum Information and Computer Science, has received a Presidential Early Career Award for Scientists and Engineers (PECASE). The honor, which is the most prestigious offered by the United States Government to young researchers, was announced July 2. More than 300 scientists and engineers around the country were recognized by PECASE this year for contributions to their respective fields, as well as for their accomplishments in scientific leadership, education, and outreach. This was the first time the award has been given out since 2017, and the winners included researchers... Continue Reading

Ring resonators corner light

Researchers at the Joint Quantum Institute (JQI) have created the first silicon chip that can reliably constrain light to its four corners. The effect, which arises from interfering optical pathways, isn't altered by small defects during fabrication and could eventually enable the creation of robust sources of quantum light.That robustness is due to topological physics, which describes the properties of materials that are insensitive to small changes in geometry. The cornering of light, which was reported June 17 in Nature Photonics, is a realization of a new topological effect, first predicted in 2017. Continue Reading

Gorshkov student, Kevin Qian, wins 2nd place in prestigious international science fair

Kevin Qian of Montgomery Blair High School placed 2nd in the Physics and Astronomy category at the International Science and Engineering Fair (ISEF) 2019 with his research topic “Heisenberg-Scaling Measurement Protocol for Analytic Functions with Quantum Sensor Networks.” Qian worked with Adjunct Associate Professor Alexey Gorshkov and graduate student researcher Zachary Eldredge in the University of Maryland Department of Physics, the Joint Quantum Institute (JQI), and the Joint Center for Quantum Information and Computer Science (QuICS).
